CMS-151125-078L100A-67

Overview

The CMS-151125-078L100A-67 is a rectangular micro speaker manufactured by Same Sky. It features a 15 x 11 mm frame with a depth of 2.5 mm and utilizes a Mylar diaphragm with a Neodymium magnet. The unit has an impedance of 8 Ohms, a rated power handling of 0.7 W (700 mW), and a frequency response range of 100 Hz to 20 kHz. It includes 100 mm leads terminated with a connector for board mounting applications.

Feature Summary

• Rectangular form factor designed for space-constrained board mount installations
• High sound pressure level output capability using neodymium magnetic technology
• Integrated lead wires with connector termination for simplified assembly

Applications

• Portable electronic devices requiring compact audio output
• Industrial control panels needing audible status indicators
• Consumer appliances with limited internal volume constraints

Procurement Notes

Verify the specific connector type on the 100 mm leads against your PCB footprint requirements before ordering. Confirm that the 0.7 W power rating aligns with your system's drive capabilities to prevent damage. Ensure the 8 Ohm impedance matches your amplifier or driver circuit specifications for optimal performance.

Selection Notes

Select this component when a rectangular shape is preferred over circular speakers for tight packaging layouts. Consider the 100 mm lead length if direct connection to distant drivers is necessary without additional wiring. Evaluate the 100 Hz to 20 kHz frequency range to ensure it covers the required audio spectrum for the intended application.

Part Context

This model belongs to the Same Sky micro speaker series, formerly associated with CUI Devices. It represents a standard solution for general-purpose audio indication in small electronics. The product line focuses on providing reliable acoustic performance within minimal physical dimensions for modern device designs.

Replacement Considerations

Check for identical dimensional constraints and electrical parameters when sourcing substitutes. Verify that alternative models support the same 8 Ohm impedance and 0.7 W power rating. Ensure replacement units offer comparable sound pressure levels and include similar lead termination methods.
